PI3B16213
3.3V, 24-Bit Bus-Exchange Switch
Product Description
Pericom Semiconductors PI3B series of logic circuits are produced
using the Companys advanced submicron CMOS technology.
The PI3B16213 is a 3.3 volt, 24-bit bus-exchange switch designed
with a low ON resistance allowing connections to be made with
minimal propagation delay. This device operates either as a 24-bit
or as a 12-bit bus switch, providing data exchange between the four
signal ports via the data-select (S0-S2) terminals.
Product Features
Near-zero propagation delay
5-ohm switches connect inputs to outputs
Direct bus connection when switches are ON
Fast Switching Speed: 5.5ns max.
Operating V
CC
Range: 3.0V to 3.6V

Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the device. This
is a stress rating only and functional operation of the device
at these or any other conditions above those indicated in
the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for ex-
tended periods may affect reliability.
Maximum Ratings
(Above which useful life may be impaired. For user guidelines, not tested.)
Notes:
1. Typical values are at V
CC
= 3.3V, T
A
= 25C ambient and maximum loading.
2. This parameter is determined by device characterization but is not production tested.
3. Measured by the voltage drop between A and B pin at indicated current through the switch. ON resistance is determined
by the lower of the voltages on the two (A,B) pins.

PI3B16213 Switching Characteristics over Operating Range
Note:
1. This parameter is guaranteed but not tested on Propagation Delays. The bus switch contributes no propagational delay other
than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone is of the
order of 0.25ns for 50pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds
very little propagational delay to the system. Propagational delay of the bus switch when used in a system is determined by the
driving circuit on the driving side of the switch and its interaction with the load on the driven side.
2. See test circuit and waveforms.
